Bad service ever

I've been wanting for my parcel for a very long time now. When tracking for it, I get messages saying contact not available but there was no communication between me and the drivers. Worse part is, when I call them, the consultants are rude and not willing to even listen to what you need to say. This morning I spoke to a very rude lady who doesn't even give you a chance to talk. It's so disappointing, they don't consider the needs of the customers, it's all about them
